Protect Yourself from Scams in the N-648 Process

USCIS does not want you to become the victim of an immigration scam involving fraudulent medical certifications for disability exception. You can read about criminal prosecutions of individuals involved in scams related to Form N-648 including Dr. Chilakamarri Ramesh; Habeeb Malik, Dr. Ira Weiner, and Dr. Thongchai Vorasingha; Dr. Roberto J.

When you seek a medical certification for disability exception because of a physical or developmental disability or mental impairment that prevents you from learning English and civics, please keep in mind the following:

• There is no filing fee for Form N-648. However, a medical professional may charge a fee for a medical examination and for filling out forms.
• Only a medical doctor, doctor of osteopathy, or clinical psychologist licensed to practice in the United States may certify Form N-648. You may contact your state medical board to determine whether the medical professional has a valid license.
• An authorized medical professional must evaluate you in person or where the state law permits, a real-time telehealth examination, and diagnose you with a condition that prevents you from completing the educational requirements in order to qualify for the N-648.
• Read and sign the Applicant’s (Patient’s) Attestation/Release of Information. A legal guardian, surrogate, or designated representative, may also sign for an applicant who is unable to undergo any part of the naturalization examination because of a physical or developmental disability or mental impairment
